Subject: [PATCH] net: phy: Add of_node_put() before return

Fix following coccicheck warning:
./drivers/net/phy/mdio_bus.c:454:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before return

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
